General information about Shelly 1 Mini Gen3 1-Channel Relay with Dry Contact

This device is a 1-channel relay designed to integrate luminaires and circuits into a lighting control system through a dry contact interface. Its compact form factor fits discreetly in recessed mounting, enabling reliable control without altering visible fixtures. With onboard conectivity via Wi‑Fi and Bluetooth, it allows flexible commissioning and local communication within control setups.

The module contributes to streamlined integration in professional and residential projects by separating command and load through the dry contact, helping adapt to diverse wiring schemes. It supports technical configuration aligned with typical voltage ranges in AC and DC, and its build in PC material provides practical durability for routine installations. Designed to strengthen system security at the wiring level, it acts as an interface component in broader lighting control topologies.

Use and applications

The primary function is switching and control of a single circuit through a dry contact, fitting projects that require compact automation points and discreet installation. It suits technical control scenarios where a recessed module is preferred, leveraging conectivity (Wi‑Fi/Bluetooth) for setup and a defined configuration path. The dry contact interface helps when galvanic isolation between command and circuit is required, ensuring clean integration in lighting boards or junction boxes.

Operation depends on available supply within the supported voltage range and the chosen recessed installation method. Commissioning can utilise Bluetooth for proximity-based setup and Wi‑Fi for networked operation, aligned with project requirements. When these conditions are met, the relay provides a practical solution for single-channel switching with a compact footprint and clear wiring logic through the dry contact interface.
